Bit of a stub. The energy comes from the same place that the primary fuels energy comes from. It's an attempt to capture loss, which happens to be made up of atmospheric pollution. IDK who says it has no carbon footprint, but whatever carbon footprint it has would already be in the atmosphere, for example, anyway.
We generally use fuel to produce more fuel, if that's what you mean by where we get the energy to get it? Doesn't really matter which specific generating plant is consuming the fuel to produce that power.
You just said a whole lot of nothing - without answering the question.
There is no free lunch. You can't make a fuel without a souce of energy. There are only three sources of energy available to us. Solar, nuclear and gravitational.
Fossil fuels are solar energy - converted by plants millenia ago.
To make a fuel from scratch as it were will take more energy from one of those sources than burning that fuel will deliver. So where is that energy going to come from? Ready for more nuke plants?
Solar from photovoltaics is a sum loss. You cannot get the energy out of them that it takes to create them.
Hydroelectric is efficient (and also solar energy) but nobody wants the enviromental impact (NIMBYISM) that goes with damming up rivers.
Windpower (also solar) is good too - but nobody wants the windmills in their neighborhood. (more NIMBYISM).
Gravitational power is limited. The only real tapping of this is in a few fjiords. Tidal action running turbines - a dam that puts out in two different directions. Reliable but limited.
